Le Gier
2 monitoring stations on this water in France, holding 1,285 values between 1964 and 2026. The publisher names the water this gauge sits on without stating what kind of watercourse it is, so neither does Hydrionis.
The monitoring network on this water
Hydrionis holds 1,285 values from 2 gauges on this water. Discharge is a property of a gauge and its reach, not of this water as a whole, so this page reports the network and its records rather than a single figure.
Every gauge Hydrionis holds here
| Gauge | Measures | Values | Record |
|---|---|---|---|
| Le Gier à Givors | mean monthly river flow | 652 | 1964–2026 |
| Le Gier à Rive-de-Gier | mean monthly river flow | 633 | 1973–2026 |
How these gauges were attached to this water
Named by the publisher Each gauge here names this water in the publisher’s own station record. Hydrionis has not inferred the connection from station names.

What this record holds
Hydrionis decides which waters get a page, and which of those are offered to search, from what is actually held rather than from how the page reads. Five signals are counted; this record has 2 of them, which makes it a profile, not indexed.
| Signal | Held | Counts |
|---|---|---|
| Gauges holding a real record | 2 | no |
| Years spanned | 63 | yes, 20 or more |
| Values held | 1,285 | yes, 1000 or more |
| Distinct measurements | 1 | no |
| Publishers measuring it | 1 | no |
| Official identifiers | 2 | recorded, not counted |
Where these figures come from
Source: Hub'Eau — Hydrométrie — French river flow and stage, V3124010. Licence: Open — attribution required (attribution required).
Method: Monthly mean discharge (QmM) computed by the publisher from its validated sub-hourly record, reported in litres per second and converted to cubic metres per second on ingestion. Where a site has been measured by more than one station, the station with the longest published series is used rather than blending stations whose values for the same month can differ.
Measured on Le Gier.
